Abstract: ABSTRACT     A process and apparatus is described for liquefying natural gas using two closed cycle. multicomponent refrigerants wherein a low level refrigerant cools and liquefies the gas by indirect heat exchange and a high level refrigerant cools and partially liquefies the low level refrigerant by indirect multistage heat exchange. The high level refrigerant is phase separated in order to use lighter refrigerant components to perform the final lowest level of refrigeration while the liquid phase of the separation is split and then expanded for refrigeration duty in order to avoid multiple flash separations wherein heavier components are used to provide the lower levels of refrigeration.

Abstract: ABSTRACT            An analog video data signal digitization and correction system scans a medium to produce video data signals representing images printed on the medium.  Two reference quantities representing analog reference signals produced by scanning a densely printed image and an area of the medium having no printed image are used to establish the maximum and minimum values of a range of possible values for each video data signal.  The analog video data sig-nals are compared with this range and a corrected digital value obtained for each data signal depending on its position in the range.  In generating the reference quantities each analog reference signal is converted into a digital reference signal dependent on the position of the analog signal in a range of possible values.  For each analog reference signal only a portion of the range of possible values is selected in order to increase the accuracy of the corresponding digital reference signal.          The number of bits in the digital reference signal is kept low but the accuracy  of each digital reference signal remains high.  In converting each digital refer-ence signal into an analog reference quantity additional high order bits are added to the digital reference signal so that each analog reference quantity has the same accuracy as its corresponding digital reference signal.

Abstract: Abstract of the Disclosure A compiler for generating an assembly language listing of instructions for a programmable data processor from a high level programming language has elements for generating from the high level programming language input, an intermediate represen-tation of the programming language input and for generating from the intermediate representation, an assembly language represen-tation of the high level programming language input.  The com-piler operates generally in accordance with the Glanville-Graham method which enables the compiler to be used with different machines.  The resulting retargetable compiler is improved by employing an up/down parsing method in the code generator portion which removes significant restrictions found when LR parsing is employed.  The parsing method allows preprocessing of the prefix grammar representing  he input intermediate representation for producing, for use by the code generator parsing element, a state table, an extended state table, and a state transition table.

Abstract: ABSTRACT :          "Amplifier arrangement".         The preamplifier (10) of an amplifier arrange-ment comprises a differential amplifier which comprises a first and a second transistor (T1, T2) between whose emitters a first resistor (R1) is arranged and whose emitters are connected to the positive power-supply terminal (2) by a first and a second current source (I1 = I, I2 = I) respectively. The collector of the second transistor (T2) is connected to the negative power-supply terminal (3) via a third current source (I3 = 3.5I) and is coupled to the output (7) of the arrangement via a second resistor (R2). Two transistors (T3, T4) having commoned bases carrying a reference voltage (VR) are ar-ranged in cascade with the third current source (I3).          The collectors of these transistors are connected to the positive power-supply terminal (2) via a fourth and a fifth current source (I4 = I, I5 = I) respectively and are coupled to the first and the second input (5,6) of the output amplifier (20) respectively. This output amplifier (20) comprises two of opposite conductivity types transistors (T5, T6) whose collectors are connected to the output (7). The resistance value of the second resistor (R2) has been so selected that the voltage on the output (7) as a result of the current flowing through this resistor (R2) in the quiescent state is equal to half the supply voltage.

Abstract: ABSTRACT Pressure limiting valves, particularly for hydraulic lining in underground mining and tunnelling secure this lining against overload, the valve body having disposed within it a spring loaded valve piston which, when overloading occurs, allows a large quantity of the pressurised medium to emerge. For this purpose, the underside of the valve spring retainer is of streamlined construction and provided in the valve body are throughflow passages which favour passage of the pressurised medium past the valve spring retainer.  Move-ment of the valve spring retainer is confined by an abutment located in the throughflow passages in order to safeguard the valve spring.  The O-ring in the groove has a smaller diameter than the radial bores.  Thus, assembly is facilitated and it is at the same time ensured that the valve responds to short lengths of travel.

Abstract: ABSTRACT      DISPLACEMENT POLYNUCLEOTIDE ASSAY EMPLOYING  RECOMBINATION PROTEIN AND DIAGNOSTIC KIT      A diagnostic reagent is disclosed containing a com-plex of a probe polynucleotide (P) bound via purine/ pyrimidine hydrogen bonding to a labeled polynucleotide (L).  The probe (P) contains a target binding region (TBR) capable of binding to a target nucleotide sequence (G) of a biological sample.  A method is disclosed in which contact with a sample containing the target nucleotide sequence (G) in the presence of a recombination protein and its cofactors causes binding, initially between G and a single-stranded portion (IBR) of the target binding region (TBR).  Thereafter the labeled polynucleotide (L) is displaced from the complex by branch migration of (G) into the (P)/(L) binding region.  Determination of displaced labeled polynucleo-tide (L) gives a value which is a function of the presence and concentration of target nucleotide sequence (G) in the sample.  The presence of the recombination protein (such as the rec A protein from the enteric bacterium E. coli) enhances the rate of appearance of displaced labeled polynucleotide, especially when the reaction is conducted at or near physiological temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE A description is given of a process for manufacturing potassium chloride with a K2O content of more than 55 wt.% from the fine salt resulting from the decomposition of carnallite.  According to this process, n-alkyl amine salts are used as conditioning agents, and flotation media containing magnesium and potassium chloride are used to separate this fine decomposition salt in an initial flotation stage into a grain size fraction of less than 0.1 mm as the first pre-concentrate and a residue having a grain size of more than 0.315 mm; following further conditioning this residue is again floated and the potassium chloride comes to the surface as a second pre-concentrate.  Next, the potassium chloride is separated from the mixture of the two pre-concentrates without any further conditioning in another flotation stage, and collected.
